Solution

The correct option is C $5.80 \times 10^{- 2} a t m$
$N H_{4} O C O N H_{2} (s) ⇋ 2 N H_{3} (g) + C O_{2}$ (g)
2x x

$K_{p} = (P_{N H_{3}})^{2} \times (P_{C O_{2}})$

$2.9 \times 10^{- 5} = 2^{2} \times x^{3}$

$x = 0.019 a t m =$ carbon dioxide pressure

So the pressure for $N H_{3}$ is twice of that according to chemical equation.

Total pressure $= (2 \times 0.0193 + 0.0193) a t m$

Total pressure $= 5.8 \times 10^{- 2} a t m$
